When I call from Client A to Client B using GW1, all works fine, its the same when hang up Client B or Client A, but when GW1 fail(I provoke it changing codec) and use failure route (GW 2) then  if Client A hang up all works fine, but the problem is when is Client B who hang up, its like a new conversation, GW 2 send BYE to openser and Openser just send "503 Service Not avilable - No gateways" to GW2, but doesnt send nothing to ClientA, any idea ????

 

Thx in advance

 

 

 

 

 

 

 

this is my basic configuration( I have attached full config file):

 

route{

 

 if (!method=="REGISTER") {
  record_route();
 };

 

 if (loose_route()) {
  append_hf("P-hint: rr-enforced\r\n");
  route(1);
 };

 

 if (!uri==myself) {
  append_hf("P-hint: outbound\r\n");
  route(1);
 };

 

 if (uri==myself) {
 
  if (method=="REGISTER") {
   save("location");
   exit;
  };

 

    if (method=="INVITE") {
                   if (!lookup("location")) {
                         if (!load_gws()) {
                                 sl_send_reply("500", "Server Internal Error - Cannot load gateways");
                                 return;
                         };                  
                 };
 
    if (!next_gw()) {
           sl_send_reply("503", "Service not available - No gateways");
                  return;
          };
 
  
  };
  };
 };

 

 t_on_failure("1");
 route(1);
}

 

route[1] {

 

 if (!t_relay()) {
  sl_send_reply("666","t_relay fallido");
  return;
 };

 

 exit;
}

 

failure_route[1] {

 

 if (!next_gw()) {
         t_reply("503", "Service not available - No gateways 1");
         return;
        };
